Detailed implementation manners

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In an embodiment according to the present invention, a learning device is provided. The learning device includes a device body, a scanning component and a control board. Among them, a storage groove is provided on the back of the device body, a display screen is provided on the front, the scanning component is slidably arranged in the storage groove, and the scanning end of the scanning component can slide out of the device body to perform scanning. When using the device body, the user can control the scanning component to slide and be stored in the storage groove, which is convenient for storage and also convenient for the user to view the content on the display screen. The following further describes the learning device in this embodiment. Figures 1 to 8 Further describe the learning device in this embodiment.

[0035] Specifically, as Figures 1 to 4 shown, the learning device in this embodiment includes: a device body 100, a scanning component 200 and a control board.

[0036] Among them, a storage groove 110 is provided on the back surface of the device body 100, and a display screen 120 is installed on the front surface of the device body 100; the scanning component 200 is slidably arranged in the storage groove 110; the control board is installed inside the device body 100, and both the display screen 120 and the scanning component 200 are electrically connected to the control board.

[0037] As the scanning component 200 slides in the storage groove 110, the scanning end 210 of the scanning component 200 can extend from the storage groove 110 to the outside of the device body 100 so as to perform scanning on the scanning medium.

[0038] Exemplarily, as Figure 1 and Figure 2 shown, the device body 100 can be configured as a rectangular parallelepiped plate-like structure with a certain thickness. The device body 100 can have a metal or non-metal shell. Inside the device body 100, there is an installation space, and various functional components such as the control board can be arranged in this installation space.

[0039] For the convenience of describing the installation positions of each component, in the device body 100 in this embodiment, there are a thickness direction, a length direction, and a width direction that are perpendicular to each other. Among them, one end face on the thickness direction side of the device body 100 is the front surface, and the other side is the back surface.

[0040] As Figure 1 and Figure 3 shown, the front surface of the device body 100 is provided with a display screen 120, and this display screen 120 can display contents such as text or video. Moreover, for the convenience of user operation, the display screen 120 can be a touch display screen, or a plurality of buttons can be provided on the front surface of the device body 100.

[0041] As Figure 2 and Figure 4 shown, the back surface of the device body 100 is provided with a storage groove 110. The storage groove 110 can be configured as a long groove that is recessed in the back surface of the device body 100. The storage groove 110 extends along the length direction of the device body 100 and penetrates from the side part in the length direction of the device body 100.

[0042] The scanning component 200 has a scanning end 210, and this scanning end 210 can perform scanning on the scanning medium. Exemplarily, the scanning component 200 can be configured as a strip-like structure with a certain length.

[0043] For the convenience of describing the installation positions of each component, similarly, the scanning component 200 also has a length direction, a width direction, and a thickness direction that are perpendicular to each other. The scanning end 210 can be arranged at one end in the length direction of the scanning component 200.

[0044] In one embodiment, as Figure 2and Figure 4 As shown, the length direction of the scanning component 200 is the same as that of the device body 100, and the width direction of the scanning component 200 is also the same as that of the device body 100. The scanning component 200 is slidably arranged in the storage groove 110. Moreover, during the sliding process of the scanning component 200, the scanning end 210 can extend out of the storage groove 110 to the outside in the length direction of the device body 100, so as to scan scanning media such as paper.

[0045] Furthermore, in this embodiment, the learning device further includes a control board, which can be made of various control chips. The control board can be fixedly installed inside the device body 100. The functional elements in the display screen 120 and the scanning component 200 are electrically connected to the control board. The user can send an operation signal to the control board through the display screen 120 or a key electrically connected to the control board, so that the control board can send a control signal to the functional elements.

[0046] In actual use, when the user needs to use the scanning component 200 to scan the scanning media, the user can extend the scanning end 210 of the scanning component 200 out of the storage groove 110 so that the scanning end 210 can reach an appropriate position outside the device body 100. After that, the user can use the scanning end 210 to scan the scanning media. When the user does not need to use the scanning media, the user can slide the scanning component 200 so that the scanning component 200 can be stored in the storage groove 110. Correspondingly, the scanning end 210 also retracts into the storage groove 110. At this time, the user can conveniently view the content through the display screen 120, or store the entire learning device.

[0047] Thus, in the learning device of this embodiment, the scanning component 200 is slidably arranged in the storage groove 110. During use, the user can slide the scanning component 200 to extend the scanning end 210 out of the device body 100 to facilitate scanning of the scanning media. The user can also slide the scanning component 200 to store it in the storage groove 110, which can facilitate the user to view the content on the display screen 120 and also make the learning device easy to store.

[0048] In one embodiment, the scanning component 200 can slide between a storage position and a scanning position. Among them, when the scanning component 200 is in the storage position, as Figure 2 shown, the scanning component 200 can be completely stored in the storage groove 110. At this time, the scanning end 210 of the scanning component 200 will not extend out from one side in the length direction of the device body 100, and the scanning end 210 is placed in the storage groove 110, and the user will not damage the scanning end 210 during use. When the scanning component 200 is in the scanning position, as Figure 4As shown, one end of the scanning assembly 200 in the length direction can extend out of the storage slot 110. At this time, the scanning end 210 of the scanning assembly 200 can extend out from one side of the device body 100 in the length direction, and the user can use the scanning end 210 to scan the scanning medium.

[0049] Further, one of the two, the slot wall of the storage slot 110 and the scanning assembly 200, is provided with a slider 220, and the other is provided with a sliding groove 111, and the slider 220 is slidably arranged in the sliding groove 111.

[0050] Exemplarily, in one embodiment, the slot wall of the storage slot 110 is provided with a slider 220, and the scanning assembly 200 is provided with a sliding groove 111.

[0051] Specifically, the storage slot 110 has two relatively arranged slot walls in the width direction of the device body 100, and at least one of the two slot walls is fixedly provided with a slider 220. The width direction of the scanning assembly 200 is the same as the width direction of the device body 100. A sliding groove 111 is correspondingly arranged on the side of the scanning assembly 200 in the width direction facing the slider 220, and the sliding groove 111 extends along the length direction of the scanning assembly 200, and the slider 220 is arranged in the sliding groove 111. For example, sliders 220 are provided on both of the two slot walls, and sliding grooves 111 are respectively arranged on both sides of the scanning assembly 200 in the width direction, and the two sliders 220 are correspondingly arranged in the two sliding grooves 111. Thus, when the scanning assembly 200 slides in the storage slot 110, the slider 220 also slides in the sliding groove 111.

[0052] Exemplarily, in yet another embodiment, as Figure 5 、 Figure 6 and Figure 7 shown, the slot wall of the storage slot 110 is provided with a sliding groove 111, and the scanning assembly 200 is provided with a slider 220.

[0053] Specifically, the storage slot 110 has two relatively arranged slot walls in the width direction of the device body 100, and at least one of the two slot walls is fixedly provided with a sliding groove 111, and the sliding groove 111 extends along the length direction of the device body 100. The width direction of the scanning assembly 200 is the same as the width direction of the device body 100. A slider 220 is correspondingly arranged on the side of the scanning assembly 200 in the width direction facing the slider 220, and the slider 220 is arranged in the sliding groove 111. For example, sliding grooves 111 are provided on both of the two slot walls, and sliders 220 are respectively arranged on both sides of the scanning assembly 200 in the width direction, and the two sliders 220 are correspondingly arranged in the two sliding grooves 111. Thus, when the scanning assembly 200 slides in the storage slot 110, the slider 220 also slides in the sliding groove 111.

[0054] It can be understood that through the above setting method, under the limiting action of the slider 220 and the chute 111, the scanning component 200 can be slidably arranged in the receiving groove 110, and moreover, the scanning component 200 can be prevented from falling off from the receiving groove 110.

[0055] Furthermore, in the present embodiment, as Figure 5 , Figure 6 and Figure 7 shown, the chute 111 is arranged on the device body 100, the slider 220 is arranged on the scanning component 200, and a driving component 300 is further arranged inside the device body 100. The driving component 300 is connected to the slider 220, and the driving component 300 can drive the slider 220 to slide in the chute 111.

[0056] Exemplarily, the receiving groove 110 has two relatively arranged groove walls in the width direction of the device body 100, and the two groove walls are both provided with chutes 111 extending along the length direction of the device body 100. Sliders 220 are respectively arranged on both sides in the width direction of the scanning component 200, and the two sliders 220 can be correspondingly clamped into the chutes 111 on both sides.

[0057] Moreover, a driving component 300 is arranged inside the device body 100, and at least one slider 220 can be connected to the driving component 300. Under the drive of the driving component 300, the slider 220 can move in the chute 111, so that the scanning component 200 can move in the receiving groove 110.

[0058] Exemplarily, in the present embodiment, as Figure 5 and Figure 6 shown, the driving component 300 includes: a lead screw module 310 and a rotary driving member 320. The rotary driving member 320 is fixedly arranged inside the device body 100. The rotary driving member 320 is in transmission connection with the lead screw of the lead screw module 310, and the slider 220 is fixedly connected to the nut of the lead screw module 310.

[0059] Specifically, the lead screw module 310 includes a lead screw and a nut. Among them, the lead screw extends along the length direction of the device body 100 and is arranged inside the device body 100. For example, as Figure 5 and Figure 6 shown, the lead screw can be arranged on the side of the chute 111. The nut is sleeved on the lead screw. The rotary driving member 320 is also fixedly arranged inside the device body 100. Among them, one end of the lead screw can be rotatably arranged inside the device body 100 by means of a support structure, and the other end is in transmission connection with the rotary driving member 320. The rotary driving member 320 can be a driving motor, and the rotary driving member 320 is electrically connected to the control board.

[0060] The slider 220 on the scanning assembly 200 is fixedly connected to the nut. For example, as Figure 5 shown, the slider 220 may have an extension plate 221 extending towards the lead screw, and the nut is provided with a connecting plate 311 extending towards the slider 220. The extension plate 221 and the connecting plate 311 are fixedly connected by structures such as screws.

[0061] In actual use, the control board can send a driving signal to the rotary driving member 320 according to the user's operation instruction, so that the rotary driving member 320 drives the lead screw to rotate in different directions, thereby driving the nut to move along the length direction of the lead screw, and finally enabling the scanning assembly 200 to slide in the receiving groove 110.

[0062] For example, as Figure 5 and Figure 6 shown, the rotary driving member 320 may be generally arranged in the middle of the device body 100. When the rotary driving member 320 drives the lead screw to rotate in the first direction, the nut can move towards the side away from the rotary driving member 320. At this time, the scanning assembly 200 can extend outwards in the receiving groove 110. When the rotary driving member 320 drives the lead screw to rotate in the second direction opposite to the first direction, the nut can move towards the side close to the rotary driving member 320. At this time, the scanning assembly 200 can retract inwards in the receiving groove 110.

[0063] Further, in an embodiment, as Figure 2 and Figure 4 shown, the learning device further includes a support plate 400. An installation groove is provided on the back surface of the scanning assembly 200, and the support plate 400 is flip - installably mounted on the groove wall of the installation groove. The support plate 400 can be flipped out of the installation groove to support the learning device.

[0064] Exemplarily, one end face in the thickness direction of the scanning assembly 200 is the front face, and the other side is the back face. The back face of the scanning assembly 200 is on the same side as the back face of the device body 100. An installation groove recessed in this end face is provided on the back face of the scanning assembly 200, and the installation groove extends along the length direction of the scanning assembly 200.

[0065] The support plate 400 is flip - installably arranged in the installation groove. In one embodiment, the support plate 400 is configured as a flat plate structure with a certain thickness. The support plate 400 has a length direction and a width direction. The length direction of the support plate 400 is the same as the length direction of the scanning assembly 200. One end of the support plate 400 away from the scanning end 210 in the length direction is rotatably mounted on the groove wall of the installation groove via a rotating shaft.

[0066] In actual use, when it is necessary to view content such as text or videos through the display screen 120 on the learning device, the support plate 400 can be flipped out from the installation groove, and the support plate 400 is used to support the learning device, so that the learning device can be placed on the table in a laterally inclined state, thereby making it more convenient for users to view the display screen 120 and operate the learning device, etc.

[0067] It can be understood that, as Figure 2 and Figure 4 exemplarily shows the installation position of the support plate 400. In practice, the support plate 400 can be set to have a certain length or width according to the size of the scanning component 200. Moreover, the support plate 400 can also be rotatably arranged in the installation groove around different rotation axes according to the installation position of the scanning component 200.

[0068] For example, the support plate 400 can be arranged in the installation groove around a rotation axis extending parallel to the length direction of the scanning component 200. Moreover, this rotation axis can be located on the side close to the scanning end 210 or on the side far from the scanning end 210. Or, the support plate 400 can be arranged in the installation groove around a rotation axis extending parallel to the width direction of the device body 100. Moreover, this rotation axis can be located on one side close to the width direction of the scanning component 200 or on the other side close to the width direction of the scanning component 200.

[0069] Further, in an embodiment, as Figure 7 shown, the learning device further includes a locking plate 500 and a torsion spring 600. The locking plate 500 is rotatably installed in the scanning component 200. The torsion spring 600 is installed between the support plate 400 and the housing of the scanning component 200. A locking hole 240 is provided on the groove wall of the installation groove, and the support plate 400 is provided with a locking block 420 adapted to the locking hole 240. The locking plate 500 can enter the locking hole 240. When the support plate 400 is received in the installation groove, the locking block 420 is clamped in the locking hole 240, and the torsion spring 600 is in a state of storing energy. As the locking plate 500 rotates, the locking plate 500 pushes against the locking block 420, pushing the locking block 420 out of the locking hole 240, and the torsion spring 600 pushes the support plate 400 out of the installation groove.

[0070] Exemplarily, the scanning component 200 can have a metal or non-metal housing, and an installation space is provided inside the housing. The locking plate 500 is arranged in this installation space. The installation groove is recessed in the surface of the housing.

[0071] In one embodiment, as Figure 7As shown in the figure, the installation groove has a groove bottom surface recessed into the back surface of the scanning assembly 200 in the thickness direction of the scanning assembly 200. The groove bottom surface is provided with through holes penetrating into the interior of the scanning assembly 200. Two mounting seats 230 are provided on the inner wall of the scanning assembly 200. On one side of the support plate 400 facing the groove bottom surface of the installation groove, two receiving seats 410 are provided. The receiving seats 410 are inserted into the interior of the scanning assembly 200 through the through holes. The mounting seats 230 are matched with the receiving seats 410 and connected by a rotating shaft. After that, the support plate 400 can be rotatably arranged in the installation groove by means of the rotating shaft.

[0072] The torsion spring 600 can be sleeved on the rotating shaft and is located between the two receiving seats 410. The two ends of the torsion spring 600 respectively abut against the support plate 400 and the scanning assembly 200. When the support plate 400 is received in the installation groove, the torsion spring 600 is in a state of storing energy. That is to say, the torsion spring 600 can exert an elastic force that causes the support plate 400 to flip out of the installation groove.

[0073] Further, after the support plate 400 is received in the installation groove, the support plate 400 can be limited by being clamped in the clamping hole 240 by means of the clamping block 420. In one embodiment, as shown in Figure 7 and Figure 8 shown in the figure, the installation groove has two relatively arranged groove walls on both sides in the width direction of the scanning assembly 200. At least one of the groove walls is provided with a clamping hole 240. The position of the clamping block 420 on the support plate 400 corresponds to that of the clamping hole 240. When the support plate 400 is received in the installation groove, the clamping block 420 can be clamped into the clamping hole 240.

[0074] In actual use, when it is necessary to receive the support plate 400 in the installation groove, the support plate 400 can be rotated so that the support plate 400 fully enters the installation groove. After the support plate 400 enters the installation groove, the clamping block 420 can be clamped into the clamping hole 240, and the support plate 400 is restricted in the installation groove. At the same time, the torsion spring 600 is compressed and in a state of storing energy. At this time, the side of the support plate 400 facing away from the groove bottom surface of the installation groove is flush with the groove opening of the installation groove.

[0075] When it is necessary to release the support plate 400 from the installation groove, the locking plate 500 can be rotated so that the locking plate 500 enters the clamping hole 240. The locking plate 500 abuts against the clamping block 420 and causes the clamping block 420 to fall off from the clamping hole 240. At this time, the support plate 400 is no longer restricted, and the torsion spring 600 can be released from the state of storing energy. Under the elastic action of the torsion spring 600, the support plate 400 can flip out of the installation groove.

[0076] Thus, in the above setting method, by setting the torsion spring 600, the support plate 400 can be more conveniently flipped out of the installation groove. Moreover, when the support plate 400 is received in the installation groove, the support plate 400 will not flip out of the installation groove by engaging the clamping block 420 into the clamping hole 240.

[0077] Further, in one embodiment, as Figure 7 shown, the learning device further includes an unlocking member 700. The unlocking member 700 is telescopically installed in the scanning assembly 200. The locking plate 500 is connected to the unlocking member 700. As the unlocking member 700 expands and contracts, the locking plate 500 rotates within the scanning assembly 200.

[0078] It can be understood that during the telescopic movement of the unlocking member 700, it can drive the locking plate 500 to rotate, converting the linear motion of the unlocking member 700 into the rotation of the locking plate 500, thereby enabling the locking plate 500 to enter or leave the clamping hole 240.

[0079] Exemplarily, as Figure 2 、 Figure 4 and Figure 7 shown, a through hole is provided on the back surface of the scanning assembly 200. The unlocking member 700 can be configured as an unlocking button provided on the back surface of the scanning assembly 200. The unlocking member 700 is telescopically arranged in the through hole along the thickness direction of the scanning assembly 200. Moreover, an annular flange is provided on one side of the unlocking button located inside the scanning assembly 200. The outer diameter of the annular flange is greater than the inner diameter of the through hole, so that the unlocking member 700 will not fall off from the through hole.

[0080] To enable the unlocking member 700 to push the locking plate 500 to move, optionally, the annular flange of the unlocking member 700 is provided with an abutting portion 710 extending towards the locking plate 500. The abutting portion 710 is provided with an abutting inclined surface on the outer side facing the locking plate 500 and inclined to the thickness direction of the scanning assembly 200. Correspondingly, the locking plate 500 is provided with a receiving inclined surface corresponding to the abutting inclined surface on the outer side facing the abutting portion 710, and the receiving inclined surface can abut against the abutting inclined surface.

[0081] In actual use, when the unlocking member 700 expands and contracts along the thickness direction of the scanning assembly 200, the abutting inclined surface can push the locking plate 500 to rotate within the scanning assembly 200 through the receiving inclined surface, so that the locking plate 500 can enter or leave the clamping hole 240.

[0082] As a specific implementation, the locking plate 500 can be arranged on the side of the unlocking member 700 along the width direction of the scanning assembly 200. An abutting portion 710 extending towards the locking plate 500 in the width direction of the scanning assembly 200 is provided on the annular flange of the unlocking member 700. An abutting inclined surface inclined to the thickness direction of the scanning assembly 200 is provided on the abutting portion 710 facing the outside of the locking plate 500. Among them, in the thickness direction from the back surface to the front surface of the scanning assembly 200, the abutting inclined surface extends obliquely from the outside to the inside in the width direction of the scanning assembly 200. A receiving inclined surface capable of abutting against the abutting inclined surface is provided on the locking plate 500 facing the outside of the abutting portion 710.

[0083] At this time, when the unlocking member 700 moves towards the inside of the scanning assembly 200, the abutting inclined surface can drive the locking plate 500 to rotate inside the scanning assembly 200 through the receiving inclined surface, so that the locking plate 500 moves towards the outside in the width direction of the scanning assembly 200, and finally the latch 420 is disengaged from the locking hole 240.

[0084] Based on this, in practice, as Figure 7 shown, when the unlocking member 700 is pressed towards the inside of the scanning assembly 200, the unlocking member 700 can drive one end of the locking plate 500 away from the locking hole 240 towards the outside in the width direction of the scanning assembly 200 under the action of the abutting inclined surface and the receiving inclined surface. At this time, one end of the locking plate 500 close to the locking hole 240 can enter the locking hole 240 to abut against the latch 420 and drive the latch 420 out of the locking hole 240.

[0085] Furthermore, in an embodiment, as Figure 7 shown, the learning device includes an unlocking and resetting member 800. One end of the unlocking member 700 is located inside the housing of the scanning assembly 200, and the other end of the unlocking member 700 is located outside the housing. The unlocking and resetting member 800 is clamped between the unlocking member 700 and the inner wall of the housing.

[0086] Exemplarily, the unlocking and resetting member 800 can be a spring. One end of the unlocking and resetting member 800 abuts against the inside of the housing of the scanning assembly 200, and the other end abuts against the unlocking member 700. The unlocking member 700 can move telescopically between a normal position and a pressing position in the thickness direction of the scanning assembly 200. The unlocking and resetting member 800 can apply an elastic force that makes the unlocking member 700 move from the pressing position towards the normal position.

[0087] In actual use, under the action of the unlocking reset member 800, the unlocking member 700 can be in a normal position. When it is necessary to drive the locking plate 500 to make the locking block 420 leave the locking hole 240, the unlocking member 700 can be pressed inward so that the unlocking member 700 moves toward the pressing position. During the process of the unlocking member 700 moving from the normal position toward the pressing position, the unlocking member 700 can drive the locking plate 500 to rotate and enable the locking plate 500 to enter the locking hole 240, allowing the locking block 420 to leave the locking hole 240. Moreover, when there is no external force pressing the unlocking member 700, the unlocking member 700 can also return from the pressing position to the normal position under the elastic force of the unlocking reset member 800.

[0088] Further, in one embodiment, as Figure 7 shown, on two opposite groove walls of the mounting groove in the width direction of the scanning assembly 200, locking holes 240 are respectively provided, and the support plate 400 is provided with two locking blocks 420, and the two locking blocks 420 respectively cooperate with the two locking holes 240 in a one-to-one correspondence.

[0089] There are two locking plates 500, and the two locking plates 500 are respectively arranged on the outer sides of both sides of the mounting groove. The middle part of each locking plate 500 is rotatably installed inside the housing. The first end of each locking plate 500 is provided with an abutting inclined surface, and the unlocking member 700 has a receiving inclined surface, and the abutting inclined surface is in contact with the receiving inclined surface. The second end of each locking plate 500 faces the locking hole 240, and as the locking plate 500 rotates, the second end of the locking plate 500 can enter and exit the locking hole 240.

[0090] Exemplarily, the number of the locking plates 500 can be two. The locking plates 500 have a certain length. The two ends in the length direction of the locking plates 500 are respectively the first end and the second end. The two locking plates 500 are respectively arranged on the opposite sides of the unlocking member 700 along the width direction of the scanning assembly 200. The middle part between the first end and the second end of each locking plate 500 is rotatably connected to the inner wall of the housing of the scanning assembly 200 via a rotating shaft. The rotating shaft extends along the thickness direction of the scanning assembly 200, and the locking plate 500 can rotate in the plane where the length direction and the width direction of the scanning assembly 200 are located.

[0091] On two opposite groove walls of the mounting groove in the width direction of the scanning assembly 200, locking holes 240 are respectively provided. The second ends of the two locking plates 500 are respectively provided with pushing blocks 510, and the pushing blocks 510 can enter and exit the locking holes 240 during the rotation of the locking plates 500.

[0092] Furthermore, the unlocking member 700 can be telescopically moved along the thickness direction of the scanning component 200, and the two locking plates 500 are respectively arranged on opposite sides of the unlocking member 700 in the width direction of the scanning component 200. At this time, under the drive of the unlocking member 700, the two locking plates 500 can rotate within the plane where the length direction and width direction of the scanning component 200 are located.

[0093] In addition, in order to enable the locking plate 500 to effectively lock the support plate 400 when the support plate 400 is stored in the installation groove, in the present embodiment, the learning device also includes an elastic member 900, and the locking plate 500 can be movably installed in the shell of the scanning component 200 through the elastic member 900, and the elastic member 900 keeps the abutting inclined surface and the receiving inclined surface in contact with each other.

[0094] Exemplarily, the elastic member 900 can be a spring, and the elastic member 900 is arranged inside the scanning component 200. The two ends of the elastic member 900 are respectively abutted against the first end of the locking plate 500 and the inner wall of the shell of the scanning component 200. The elastic member 900 can exert an elastic force that makes the abutting inclined surface and the receiving inclined surface fit each other, so that the second end of the locking plate 500 is away from the card hole 240, so that the locking plate 500 can automatically reset after pushing the card block 420 out of the card hole 240.

[0095] Specifically, in this embodiment, the locking plate 500 rotates to switch between the locking position and the release position. After the support plate 400 is received in the installation groove, the locking plate 500 is located in the locking position, and the block 420 on the support plate 400 can be engaged with the engagement hole 240. At this time, the push block 510 at the second end of the locking plate 500 can be away from the engagement hole 240; the elastic member 900 pushes the locking plate 500 so that the abutting inclined surface and the receiving inclined surface are kept in contact. When the locking plate 500 rotates to the release position, the push block 510 at the second end of the locking plate 500 can enter the engagement hole 240, and the block 420 can be separated from the engagement hole 240. At this time, the support plate 400 can be turned over to the outside of the installation groove without interference. Among them, the elastic member 900 releases the elastic force, pushing the locking plate 500 to transfer from the release position to the locking position, and realizing reset, so as to prepare for the next pop-up of the support plate 400.

[0096] In another embodiment, when the elastic member 900 is not provided, the push block 510 at the second end of the locking plate 500 can enter the locking hole 240 and can cause the locking block 420 to be disengaged from the locking hole 240, thereby allowing the support plate 400 to flip to the outside of the installation slot. After the support plate 400 is stored in the installation slot next time, the locking block 420 on the support plate 400 can enter the locking hole 240 and can push the push block 510, and can push the locking plate 500 back to the locked position.
